A mathemetical model of magnetic field in electromagnetic separation of inclusions from molten aluminum under rectangle coil and 50Hz current is presented according to the magnetic vector potential integral equation and the basic theory of magnetohydrodynamics. The magnetic field distribution in the gap of coils is simulated by the model and the actual magnetic field distribution also is measured. The experimental results show that the magnetic field distribution in the gap of coils is uniform and is consistemt with the model simulation. The magnetic field designed accord the simulated result is proved suitable in the practice.

By research on the concentration change and distribution of methyl bromide in the container, we found that in the first period of fumigating, the absorption of the goods to methyl bromide became quickly, so did the concentration decline of the fumigant because of leakage of the carton itself. The distribution of the fumigant is not uniform in the aclinic and vertical directions. The absorption of the goods to methyl bromide completed after 6 hours delivered the gasified fumigant and the distribution of the concentration in space got balance.
